Re: Diamond planet


I'm sure that De Beers is thinking about how to keep folks from wanting to exploit THAT particular resource. Tongue

However, even provided we could even GET there, our only hope of mining anything on the planet would rely on that planet being tidally locked to the star, and us being able to descend/ascend in a straight line, perpendicular to the planet's surface. And given t hat it's 8 times the mass of the Earth, an "at rest" state would already be experiencing 8g's, so taking off "straight up" would require nearly ten times that much force in acceleration (I'm figuring 70-75g's, or there about), just to take off. sounds just a little SciFi, right now, though it's fun to think about.

Re: Diamond planet


Diamond is good but wouldn’t it be better if they found a planet made of chocolate, mmmm, or is that just me  Cheesy

Good find Syber  Smiley

Chocolate would be good, was never a fan of Butterscotch custard, but if I could have a choice? Can you say super sized cheesy puff  Tongue

Dave I don't think they could get a ship to take off from that size of a planet, I think the ship would collapse like a tin can. I think they would have to build an elevator of some sort.

Re: Diamond planet


If I see any chocolate planets I will be sure to let you know Data.  lol

Re: Diamond planet


Yeah, I DO seem to recall mentioning the term "SciFi" somewhere in there. Tongue

This would depend on the density of the planet and therefore how close you are to the center. Assuming similar or greater density to Earth 5-8g is not unreasonable though.
All you need is constant acceleration to lift of. It could be done from Earth at 1.1g but would take ages and lots of fuel. Typically, from Earth, they take off at 3-5g (upto 7-10 for unmanned) so as to use less fuel and not to kill/cripple the passengers. Again, this depends on your Vc or Ve you wish to obtain (c=circular (in orbit) e=escape velosity). For Earth, Vc is typically 17,000MPH and Ve is 25,000MPH.
Soooo, if 5g with a radius of 5,000 miles (Earth is 4,000), Ve would be 63,000MPH. Or a lot of fuel. But if we managed to get there, then I doubt that would be a problem. The 5g on the planet would be, like, heavy man. But nothing a warp bubble couldn't stop.  Cheesy

Also, the article says...
"In fact, the planet, dubbed 55 Cancri e, appears to have no water at all. And as much as one-third of the planet‘s substantial mass could be made of diamond" (my italics). They are, basically, guessing.
